Guidance on Safe Use
Administrative data
First-aid measures
Pay attention to self-protection.
Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a
stabilized position and covered.
Do not leave victims unattended.
If the casualty is unconscious: Place the victim in the recovery position.
Inhalation
Potential for exposure by inhalation if dusts or smoke are generated.
Move victims into fresh air.
With labored breathing: Provide with oxygen. Consult a doctor.
If the casualty is not breathing: Perform mouth-to-mouth resuscitation, notify emergency physician immediately.
Skin contact
Wash off affected area immediately with plenty of water for at least 15 minutes.
If symptoms persist, consult a physician for treatment.
Eye contact
With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.
Inform emergency physician immediately. (key term: caustic eye burn)
Ingestion
Rinse mouth.
Immediately give large quantities of water to drink.
Inform emergency physician immediately.
Most important symptoms and effects, both acute and delayed
Hazards
Strongly irritating to corrosive.
Indication of any immediate medical attention and special treatment needed
The initial focus is only on the local action, characterized by quickly progressing deep tissue damage.
Coughing is a symptom of respiratory tract after inhalation of dusts or smoke from caustic solids.
In the eye, caustic dusts or smoke cause, depending on the intensity of exposure, severe irritation, destruction, and ablation of the epithelium of the
conjunctiva and cornea, corneal clouding, edema and ulcerations.
Danger! Possible loss of eyesight!
Superficial irritations and damage up to ulcerations and scarring develop on the skin.
Fire-fighting measures
Suitable extinguishing media: dry sand, dry powder, Alcohol-resistant foam
Unsuitable extinguishing media: water, foam, CO2, water spray, high volume water jet, Halons
Special hazards arising from the substance or mixture
Reacts violently with water and foam.
In case of fire-fighting with water or foam be aware of dangers of corrosion and of slipping.
Combustion residues must be disposed of properly.
Advice for firefighters
Water for fire fighting must not be introduced in the sewer system, subsoil, or surface waters. Assure that there are sufficient fire water retaining
facilities Contaminated fire fighting water must be disposed of in conformity with the regulations of the local authorities.
Fire residues should be disposed of in accordance with the regulations.
In case of fire: full protective suit and wear a self contained respiratory apparatus
Accidental release measures
Use personal protective equipment.
Avoid dust formation.
Keep away from sources of ignition - No smoking.
Environmental precautions
Do not allow entrance in sewage water, drainage systems, stretches of water, soil.
Observe regulations on prevention of water pollution (check, dam up, cover up).
Methods and material for containment and cleaning up
Cover with dry sand.
Use mechanical handling equipment.
Suitable binder: dry sand
Reference to other sections
Wear personal protective equipment
Handling and storage
Avoid residues of the product on the containers.
Under inert gas (argon, nitrogen).
in case of leakage: Wear personal protective equipment. Provide good ventilation or extraction.
Conditions for safe storage, including any incompatibilities
Advice on protection against fire and explosion
Take precautionary measures against static discharges.
Keep away from sources of ignition - No smoking.
No sparking tools should be used.
Avoid dust formation.
If dusts develop, explosive dust/air mixtures may form.
Storage
Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.
Protect from warming.
Avoid humidity and water.
Storage under inert gas (nitrogen) recommended.
Suitable materials: stainless steel
Unsuitable materials: light metals and their alloys
Further information
In order to ensure due transportation, make certain that stacks are of the correct height, containers are securely fastened so as not to fall off, and labelled according to the regulations.
